The slip ring chamber is the key part where the carbon brush contacts the slip ring in the double-fed generator. During operation, high temperatures will be generated due to friction and current conduction. The cooling fan is forced to ventilate to prevent oxidation of the slip ring, abnormal wear of the carbon brush or insulation aging caused by overheating. Meanwhile, carbon dust will be generated due to wear of the carbon brush. The fan airflow can discharge it or guide the filter to avoid short circuits or creepage caused by carbon deposition.
